I have three windows side by side that have no molding in between. I was wondering if you can get three separate blinds with one valance covering them all? or if you can get a three on one headrail blind with one valance?

Our camper has blinds that have a cord which is secured to the bottom on the walls. The blind raises and lowers by pushing the blind up or down on that cord and the cord does not move. Do you sell that type of blind?
